9VAC5-40-5670. Motor vehicles.

A. Emission control systems.

1. No owner or other person shall cause or permit the removal, disconnection or disabling of a crankcase emission control system or device, exhaust emission control system or device, fuel evaporative emission control system or device, or other air pollution control system or device which has been installed on a motor vehicle in accordance with federal laws and regulations while such motor vehicle is operating in the Commonwealth of Virginia.

2. No owner or other person shall attempt to defeat the purpose of any such motor vehicle pollution control system or device by installing any part or component which is not a standard factory replacement part or component of the device.

3. No motor vehicle or engine shall be operated with the motor vehicle pollution control system or device removed or otherwise rendered inoperable.

4. The provisions of this section shall not prohibit or prevent shop adjustments or replacement of equipment for maintenance or repair, or the conversion of engines to low polluting fuels such as, but not limited to, natural gas or propane.

B. Visible emissions.

1. No owner or other person shall cause or permit the emission of visible air pollutants from gasoline-powered motor vehicles for longer than five consecutive seconds after the engine has been brought up to operating temperature.

2. No owner or other person shall cause or permit the emission of visible air pollutants from diesel-powered motor vehicles of a density equal to or greater than 20% opacity for longer than 10 consecutive seconds after the engine has been brought up to operating temperature.

C. In commercial or residential urban areas, propulsion engines of motor vehicles licensed for commercial or public service use shall not be left running for more than three minutes when the vehicle is parked, unless the propulsion engine is providing auxiliary power for other than heating or air conditioning; except that:

1. Tour buses may idle for up to 10 minutes during hot weather in order to maintain power to the air conditioning system; and

2. Diesel powered vehicles may idle for up to 10 minutes to minimize restart problems.

9VAC5-40-5680. Other mobile sources.

A. General. All mobile sources operating within Virginia, including the air space over this Commonwealth, shall control their emissions in strict accordance with the applicable federal laws and regulations.

B. Visible emissions. The provisions of 9VAC5-40-80 shall apply to the discharge of visible emissions from all mobile sources, unless specified otherwise in subsection C of this section.

C. Exceptions.

1. Aircraft. Subsection B of this section shall not apply to aircraft.

2. Diesel locomotives. Visible emissions from operating diesel-powered locomotives shall not exceed a density greater than 30% opacity unless the locomotive is operating under any of the following conditions:

a. Accelerating under load, and then only for a maximum of 40 consecutive seconds for stabilization of the new operating condition;

b. Being loaded after a period of idle, and then only for a maximum period of four consecutive minutes after the changed condition;

c. Started cold, and then only for a maximum of 30 consecutive minutes after such a start; or

d. Being tested, adjusted, or broken in after rebuilding or repair, and then only for maximum periods of 3 consecutive minutes for an aggregate of no more than 10 minutes in any 60-minute period.

3. Ships and other watercraft. Visible emissions in excess of subsection B of this section are authorized when not at dock and for brief periods when at dock under the following conditions:

a. During dock trials as required to test and calibrate the ship's machinery control systems;

b. When lighting off a cold machinery plant and getting under way;

c. When used on shore to simulate dock or sea trials; or

d. When soot blowing. Soot blowing shall be limited to once in each 24-hour period and shall be allowed only when wind conditions and direction are such as to prevent a public nuisance or hazard to the health and safety of persons and property both ashore and afloat.

4. Other diesel-powered mobile sources. Visible emissions from diesel-powered mobile sources which are not otherwise governed by these regulations shall not exceed 20% opacity for longer than 10 consecutive seconds after the engine has been brought up to operating temperature.
